New role identified for astrocytes in brain processing.

The brain is comprised of billions of brain cells, a vast network of synapses and neurons transmitting electronic impulses like many stars in an infinite universe. A crucial support system … Continue Reading New role identified for astrocytes in brain processing.

Neuroimaging shows how the brain switches from past to present memory mode.

The hippocampus is a critical structure for encoding of novel experiences. A particularly compelling puzzle is how the hippocampus encodes new information in the presence of interference from past memories.  … Continue Reading Neuroimaging shows how the brain switches from past to present memory mode.

Researchers purify and grow human astrocytes-in-a-dish for the first time ever.

Astrocytes are star-shaped glial cells in the brain and spinal cord.  They perform many functions, including biochemical support of endothelial cells that form the blood–brain barrier, provision of nutrients to … Continue Reading Researchers purify and grow human astrocytes-in-a-dish for the first time ever.

Researchers identify how the blood-brain barrier is maintained to control ‘tight junction’ function.

It has long been known that the brain is protected from alterations elsewhere in the body by a highly regulated gateway known as the blood-brain barrier, which allows only selected … Continue Reading Researchers identify how the blood-brain barrier is maintained to control ‘tight junction’ function.
